Works good.
The new impeller revived our dead pump. It was easy to install and fit perfectly. The water in our bird pond is flowing again. The little tweeters are happy to find running water in the winter.

without this product I would be in big trouble!
Upon installing the first Mag Drive magnet ,the force jammed and and broke the plastic shaft. After a call to customer service at doctor Foster and Smith I had a new Mag drive propeller within 3 days. The service was more than what i expected. I will continue to do whatever business I need to do with Doctors Foster and Smith.

The part works great
It was shipped in a timely manner. The impeller was very easy to replace and the pump is working good as new again but the original one did not last nearly as long as those in the larger pumps.

A fine product
In working with pond pumps for 17 years and often having up to 4 pumps running at the same time for different purposes, I find that these Mag-drive pumps do the job at the best price and energy consumption level. In fact I have yet to find any pump that is more efficient than the models sold here. As far as keeping them going for way more than the three year warranty, I have done so by adding washers to the bottom shaft to lift the impeller, changed the impeller and cover when needed and pretty much just keeping them clean. I believe you can keep these pumps running for at least 10 years with the help from the parts people and a little mechanical ability. Everything else is more expensive to buy and operate.

Answer:

It depends on how many hours or age it has on it. After three years of near continuous work they can need some washers put in to keep the impeller from contacting the cover. I have been able to keep some pumps going for 8 or 9 years with some small fixes. I would start by taking it apart and cleaning it so that there is no crud stopping the rotation that has gotten into it or built up over time. You can learn a lot about the problem if you open them up and have a look inside. Also find out if there is too much restriction of flow as that could cause it to overheat.

The impeller is a good place to start. However, the race that it runs in may be worn and out of round. If it appears egg-shaped or oval, a new impeller may wear out fast. I have replaced impellers in smaller pumps with a worn race with success because the replacement impeller came with new end bushings that help keep it centered. It is worth it to repair, but the impeller may not last as long if the race is worn.

Answer:

Generally, you can tell by the size of them since they only made so many models. I have about 6 mag drive pumps in the pond and one on a failed Fluval filter which is now being used with the 350 gallon/Hr pump. It works much better than the original Fluval pump. It all depends on how many pumps you have purchased and you can select from the sizes of those. There are 2400g/Hr, 1800g/Hr, 1200g/Hr and then smaller ones. I use mostly larger ones for my pond.

I would like to know where to buy the rubber end caps for the 1800 impeller as I have some that have worn out and they do not come with the impeller or the cap part? This is the first one that has worn through but now I am interested in a dozen of them- without this part, the new impeller is not worth buying.
